What is this test?

A face CT with intravenous contrast is an X-ray-based imaging test that creates detailed pictures of the face, skull, sinuses, soft tissues, and nearby blood vessels. IV contrast helps highlight structures and may show inflammation, infection, injury, or masses more clearly.

Why might I need this test?

Your clinician may order this test to evaluate facial pain or swelling, sinus problems, trauma, infection, a suspected mass, or the cause of symptoms involving the eyes, nose, jaw, or surrounding tissues.

How is the test performed?

You will lie on a CT scanner table while X-ray images are taken from different angles. For the contrast portion, an IV line is placed in your arm and a special dye is injected, usually followed by additional images.

How do I prepare for the test?

Follow your clinician's instructions, which may include avoiding eating or drinking for a few hours beforehand. Tell the imaging team about kidney disease, prior contrast reactions, iodine or shellfish allergies, pregnancy or breastfeeding, and any medications such as metformin.

Frequently asked questions

Is this CT scan painful?
The scan itself is generally painless. The IV injection may cause a brief warm or cool sensation, and you may feel pressure when the needle is placed.
How long does a CT face with IV contrast take?
The examination usually takes less than 30 minutes, although exact timing varies. You may be asked to remain in the imaging area briefly afterward for observation.
Will I be exposed to a small amount of radiation?
Yes. CT scans use ionizing radiation, but the dose is generally kept as low as reasonably achievable for the needed images. IV contrast adds no radiation.
